looking for a particular story

I remember reading a story a while ago but unfortunately didn't save it and now i can't find it

bits i remember,

an around teenage boy saw a dress in a window of a boutique and became obsessed with it
owner of boutique convinced him to wear it and go to a salon

as payment owner convinced/blackmailed the boy into participating in a parade on a float, and then attend a ball/dance at some sort of community centre

unfortunately i don't even remember if the story was on this site or another, if anyone has a clue i would be very greatful

thanks
